fetch values via http

Hello,
can I gather some data with the dude from http and make a data source from it?
My output is plain text and looks like this:

"wireless": {
	"mode": "sta",
	"essid": "SOME-ESSID",
	"hide_essid": 0,
	"apmac": "00:15:6D:00:00:00",
	"channel": 36,
	"frequency": "5180 MHz",
	"opmode": "11naht40plus",
	"antenna": "17x24",
	"chains": "1X1",
	"signal": -63, "rssi": 33, "noisef": -95,
	"ack": 37,
	"distance": 1950,
	"ccq": 1000,
   etc...

thank you
B.
